Jun 15, 2026 · What Is NVLink And How Does It Differ From SLI ? If you're wondering what happened to SLI and the idea of connecting multiple GPUs for a better performance, we have the answer - NVLink .
Jan 27, 2026 · NVLink 5.0 offers much more bandwidth than UALink 1.0’s per-GPU bandwidth at 1.8 TB/s versus 800 Gb/s. For workloads where raw communication speed between adjacent GPUs drives performance, this gap is significant. UALink counters with more cluster scalability. Support for 1,024 accelerators versus NVLink ’s 576 gives organizations building massive training clusters more headroom, and the ...
Feb 7, 2024 · NVLink is a technology developed by NVIDIA for high-speed point-to-point interconnectivity between GPUs (and also between GPUs and CPUs). It aims to overcome the bandwidth limitations of PCIe interconnects and enable low-latency, high-bandwidth data communication between GPU chips, allowing them to work more efficiently in tandem.
